5 X 105 ficoll prepared human peripheral white blood cells were washed and preincubated 5 minutes with 20 uL of 250 ug/mL human IgG (to block non specific binding) after which they were incubated 45 minutes on ice with 80 uL of CD27 monoclonal antibody, clone M-T271 (Cat # MAB6903) at 10 ug/mL. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. A net 64% sub population of the cells stained positive with a mean shift of 1.0 log10 fluorescent units when compared to a Mouse IgG1 negative control at a similar concentration.

The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for generation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. This receptor transduces signals that lead to the activation of NF-kappaB and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process of this receptor. CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor. [provided by RefSeq
